Summary of "Antiviral agents 3. Discovery of a novel small molecule non-nucleoside inhibitor of Hepatitis B Virus (HBV)."

The discovery of a small molecule non-nucleoside inhibitor of Hepatitis B Virus is described. During our work on conocurvone derived naphthoquinone 'trimers' for the treatment of HIV, we discovered a potent inhibitor 9 of Hepatitis B Virus in an antiviral screen. During attempts to resynthesis 9 for proof of concept studies, we altered the synthesis in order to attempt to reduced side reactions and difficult to remove by-products. As a result we discovered a small molecule 19 that also was a potent inhibitor of HBV. Importantly, this small molecule inhibitor of Hepatitis B Virus is also an inhibitor of Hepatitis B Virus resistant to 3TC, a bench mark of nucleoside analogues active in the treatment of Hepatitis B Virus. The development of 19 as an agent to treat HBV infections is discussed.

Medical and Biotech [MESH] Definitions

Nevirapine

A potent, non-nucleoside reverse transcriptase inhibitor used in combination with nucleoside analogues for treatment of HIV infection and AIDS.

Riboswitch

Part of a MESSENGER RNA molecule that undergoes a conformation change upon binding a specific metabolite or other small molecule thereby regulating the messenger RNA's transcription, post-transcriptional processing, transport, translation, or stability in response to varying levels of the metabolite or other small molecule.

Nucleoside-phosphate Kinase

An enzyme that catalyzes reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside monophosphate, e.g., UMP, to form ADP and UDP. Many nucleoside monophosphates can act as acceptor while many ribo- and deoxyribonucleoside triphosphates can act as donor. EC 2.7.4.4.

Ribavirin

A nucleoside antimetabolite antiviral agent that blocks nucleic acid synthesis and is used against both RNA and DNA viruses.

Dinucleoside Phosphates

A group of compounds which consist of a nucleotide molecule to which an additional nucleoside is attached through the phosphate molecule(s). The nucleotide can contain any number of phosphates.
